[0002] At present, the basic structure of the carding machine on the market consists of four parts: feeding mechanism, pre-carding mechanism, main carding mechanism and stripping mechanism. Carding is one of the important processes in wool top manufacturing. Its main task is to gradually decompose the clumps of fibers into single fibers to form relatively straight and parallel wool tops. At the same time, the raw materials are mixed and weeds are removed. In the process of processing the clumps of fibers into wool tops, the fiber length will be damaged to a certain extent, and lint will be produced in the wool tops. lint is a small fiber entanglement produced in the carding process of wool tops. It appears as spots or small balls in the wool net and wool tops, which not only affects the appearance quality of the combed wool yarn, but also affects the appearance quality of the fabric and forms dyeing defects.

[0003] The main reasons for the appearance of fuzz in the carding machines currently on the market are: poor opening effect, impurities are removed before the fibers are fully loosened, and fuzz is formed after repeated combing; the card clothing is designed unreasonably and has poor self-cleaning ability, which leads to grass thorns on the card clothing and a large return load, which leads to an increase in fuzz and damage to the fibers; the impurity removal efficiency of the impurity removal system is low, and when the opening is insufficient, impurities are transferred in the fiber web to form fuzz; there are too many combing mechanisms, which leads to repeated transfer and rubbing of fibers to form fuzz.

[0035] At present, the basic structure of the carding machine on the market consists of four parts: feeding mechanism, pre-carding mechanism, main carding mechanism and stripping mechanism. Carding is one of the important processes in wool top manufacturing. Its main task is to gradually decompose the clumps of fibers into single fibers to form relatively straight and parallel wool tops. At the same time, the raw materials are mixed and weeds are removed. In the process of processing the clumps of fibers into wool tops, the fiber length will be damaged to a certain extent, and lint will be produced in the wool tops. lint is a small fiber entanglement produced in the carding process of wool tops. It appears as spots or small balls in the wool net and wool tops, which not only affects the appearance quality of the combed wool yarn, but also affects the appearance quality of the fabric and forms dyeing defects.

[0036] The main reasons for the appearance of fuzz in the carding machines currently on the market are: poor opening effect, impurities are removed before the fibers are fully loosened, and fuzz is formed after repeated combing; the card clothing is designed unreasonably and has poor self-cleaning ability, which leads to grass thorns on the card clothing and a large return load, which leads to an increase in fuzz and damage to the fibers; the impurity removal efficiency of the impurity removal system is low, and when the opening is insufficient, impurities are transferred in the fiber web to form fuzz; there are too many combing mechanisms, which leads to repeated transfer and rubbing of fibers to form fuzz.

[0037] See also Figure 1 , Figure 2 as well as Figure 3 The present invention provides a worsted carding machine 100 for reducing lint particles, comprising a wool feeding and combing structure, the wool feeding and combing structure comprising a wool feeding mechanism 1 and a cylinder mechanism 2; the wool feeding mechanism 1 comprises a feeding roller 11, a wool feeding plate 12 and a feeding transfer roller 13, the wool feeding plate 12 is arranged below the feeding roller 11, the feeding transfer roller 13 is arranged in front of the feeding roller 11, the wool feeding plate 12 is used to carry fiber material, the feeding roller 11 is used to rotate and convey the fiber material forward, the feeding transfer roller 13 is used to rotate to receive the fiber material and rotate and convey it forward; the cylinder mechanism 2 comprises a cylinder 21 and a plurality of combing units 22, the cylinder 21 is arranged in front of the feeding transfer roller 13, the plurality of combing units 22 are arranged in sequence along the circumference of the cylinder 21, the cylinder 21 is used to rotate to grab fiber bundles from the fiber raw material on the feeding transfer roller 13, and convey them in sequence through the plurality of combing units 22.

[0038] The present invention provides a worsted carding machine 100 for reducing lint particles. In the worsted carding machine 100 for reducing lint particles, a feeding plate 12 is added below the feeding roller 11. During the use of the worsted carding machine 100 for reducing lint particles, fiber material is fed onto the feeding plate 12 and conveyed forward, the feeding roller 11 rotates, the fiber material is gripped by the needle cloth on the feeding roller 11, the fiber material is grabbed from the feeding plate 12 and pulled forward, the spacing between the feeding roller 11 and the cylinder transfer roller 13 is greatly reduced, and the gripped fiber material is loosened by the feeding roller 11, the cohesive force in the fiber material is reduced, the looseness is increased, and the generation of lint particles is effectively alleviated.

[0039] Furthermore, a roller cloth is arranged on the outer wall of the feed roller 11, and metal needle teeth are formed on the roller cloth. The cross section of the metal needle teeth is gradually reduced from the inside to the outside, and the end of the metal needle teeth is arranged in a plane. In this embodiment, the feeding roller 11 cloth is replaced, and the feeding roller 11 cloth is arranged in a flat-headed pagoda shape, which can reduce fiber damage and enhance the opening effect of the feeding roller 11.

[0040] On the other hand, the combing unit 22 is used to comb the fiber bundle on the cylinder 21. Specifically, the combing unit 22 includes a combing stripping roller 221 and a combing transfer roller 222. The cylinder 21 and the combing transfer roller 222 have a combing effect. A part of the fibers are taken out of the combing unit 22 by the cylinder 21, and the other part is grabbed by the combing transfer roller 222, and reversely stripped by the combing stripping roller 221 and brought to the cylinder 21. Then, the cylinder 21 strips the fibers from the combing stripping roller 221 in the same direction and mixes them with the newly fed fibers and the fibers on the cylinder 21 that have not been transferred out of the machine, so as to achieve straightening, parallelization and uniform mixing of the fibers.

[0041] On the other hand, a metal card cloth is arranged on the cylinder 21. In this embodiment, the metal card cloth can effectively improve the combing effect of the fiber, reduce the generation of lint during the fiber combing process, solve the combing problems of the fiber containing a lot of impurities, grass thorns, large transfer load, difficult separation, and easy breaking, improve the fiber grabbing and transfer efficiency, stabilize the grabbing and transfer capabilities, reduce the damage of the fiber during the combing process, and improve the opening effect.

[0042] Similarly, the outer wall of the combing stripping roller 221 is provided with metal needle clothing. In this embodiment, the needle clothing on the combing stripping roller 221 is set as metal needle clothing. Since the stripping roller on the original cylinder is a brush, the brush can only play the role of cleaning and basic fiber transfer, but has no opening effect. The brush of the stripping roller on the cylinder is replaced with metal needle clothing to enhance the one-time fiber transfer force and improve the opening effect. It should be noted that, please refer to Figure 4In this embodiment, the metal card clothing is composed of a card clothing base 05 and a plurality of card clothing serrations arranged on the card clothing base 05, and the card clothing serrations include a card clothing working top surface 01, a card clothing working end surface 02, a card clothing working back surface 03 and a card clothing working bottom surface 04. The card clothing working top surface 01 is composed of a straight line, and the card clothing working end surface 02, the card clothing working back surface 03 and the card clothing working bottom surface 04 are all composed of a combination of a straight line and an arc line.

[0043] Furthermore, the cylinder mechanism 2 also includes a cylinder smooth roller 23, which is arranged between the feeding transfer roller 13 and the plurality of combing units 22.

[0044] On the other hand, in this embodiment, the feeding roller 11 rotates counterclockwise, and the feeding transfer roller 13 rotates counterclockwise, so as to facilitate the grabbing and conveying of the fiber material.

[0045] In the worsted wool combing machine 100 for reducing wool particles provided by the present invention, two wool feeding and combing structures are provided, including a first wool feeding and combing structure and a second wool feeding and combing structure arranged in sequence from a processing direction, and a conveying and feeding mechanism 3 is also provided between the first wool feeding and combing structure and the second wool feeding and combing structure for conveying the fiber bundle output by the first wool feeding and combing structure to the second wool feeding and combing structure.

[0046] In this embodiment, in the first wool feeding and combing structure, the cylinder is a breast cylinder; in the second wool feeding and combing structure, the cylinder is a main cylinder; thereby, a two-stage cylinder is obtained for worsted combing.

[0047] See also Figure 5In the present embodiment, the conveying and feeding mechanism 3 comprises a breast cylinder transfer roller 31, a breast cylinder doffer 32 and a conveyor belt 33; the breast cylinder transfer roller 31 is arranged in front of the cylinder 21 of the first wool feeding and combing structure, the cylinder 21 of the first wool feeding and combing structure rotates and sequentially conveys through a plurality of the combing units 22 and the breast cylinder transfer roller 31, the breast cylinder transfer roller 31 is used to transfer the fiber bundle on the cylinder 21 of the first wool feeding and combing structure; the breast cylinder doffer 32 is arranged in front of the breast cylinder transfer roller 31, used to obtain the fiber bundle on the breast cylinder transfer roller 31 to form a fiber web, and an air flow blowing device 321 is provided at the upper end of the breast cylinder doffer 32, used to blow off the fiber web on the breast cylinder doffer 32; the conveyor belt 33 is arranged in front of the breast cylinder doffer 32, used to carry and convey the blown-off fiber web, and convey it to the wool feeding plate 12 of the second wool feeding and combing structure. The original impurity removal system is a passive impurity removal system. It is only when the fibers are fully opened that the impurities on the surface of the wool net can be grabbed and removed. However, when the fibers are not sufficiently opened, the impurity removal efficiency is very poor, and the impurities are transferred in the fiber net to form wool particles. In this embodiment, the replaced conveying and feeding mechanism 3 is composed of the breast cylinder transfer roller 31, the breast cylinder doffer 32 and the conveyor belt 33, which can effectively reduce the formation of wool particles during transfer in the fiber net.

[0048] It should be noted that the airflow blowing device uses airflow to blow off the fiber web on the chest cylinder Lindorfer. There are many implementation methods, as long as the airflow can be emitted to peel off the fiber web, and no specific limitation is made here.

[0049] Specifically, in this embodiment, the breast cylinder transfer roller 31 rotates counterclockwise, and the breast cylinder doffer 32 rotates clockwise.

[0050] Among them, see Figure 6 The cylinder mechanism 2 of the second feeding and combing structure includes a main cylinder; the cylinder mechanism 2 of the second feeding and combing structure includes five combing units 22. In this embodiment, too many working rollers and stripping rollers on the main cylinder will cause repeated transfer and rubbing of fibers, eventually forming lint. Reducing the number of working rollers and stripping rollers on the main cylinder not only alleviates the lint problem, but also reduces the burden on the motor, saving energy and reducing consumption.

[0051] Similarly, the worsted carding machine 100 for reducing wool particles also includes a doffer 41, which is arranged in front of the cylinder 21 of the second wool feeding and combing structure, and is used to obtain the fiber clusters on the cylinder 21 of the second wool feeding and combing structure to form a fiber web. A chopping knife 42 is provided at the upper end of the doffer 41 for chopping off the fiber web on the doffer 41.
